Diesel exhaust has been linked
to a lot of health problems –
asthma, heart disease, and cancer.
That’s why so many states and cities
across the country have anti-idling
laws for diesels. Mark Brush reports
some bus companies are being caught
with their engines running:

In Connecticut and Rhode Island , the Environmental Protection Agency caught a bus company called First Student breaking anti-idling laws. In some cases, they found bus drivers idling their engines for up to two and a half hours.

The government just reached a settlement with First Student. Tim Conway is an enforcement lawyer for the EPA.

“First Student really stepped up to the plate once we’d identified the violations. And they helped us look for solutions that would protect children’s health and protect the health of people around the diesel vehicle.”

First Student is now retraining their drivers and cleaning up their emissions. The company operates buses in 40 states.

There are still a lot of states that don’t have any restrictions on diesel idling. So, on any given school day, you can find long lines of buses polluting the air in front of schools, waiting for the kids to come out.

Getting Water to the Dry, Dry West

  • Colorado Springs pumps water through the Rocky Mountains into town (Photo courtesy of the Colorado Springs Convention and Visitors Bureau)

Out West, a lot of cities figure many more people will be moving in over the next few decades.

Out West, a lot of cities figure many more people will be moving in over the next few
decades. Water engineers wish those people would bring along all the water they’ll
need, but of course they won’t. Shawn Allee reports these cities want to pipe more
water from far away, and some people think that’s a bad idea:

The air in Colorado Springs is usually so dry it quickly chaps your lips.

What gives? Colorado Springs sounds wet enough.

“There’re really no springs in Colorado Springs, so when you start talking
about water, it’s a divergence between our name and reality. Sounds like we
had a lot, and in reality we didn’t.”

This is Matt Mayberry, Colorado Spring’s historian.

I’ve heard about this massive water pipeline project the town’s cooking up, and I was
curious just how long the city’s worked to quench its thirst.

Mayberry’s got an exhaustive book on that with an exhaustive title.

“Blah, blah, blah … the emergence and appropriation of rights in Colorado
Springs.”

The crib notes version?

Early on, buffalo manure poisoned Colorado Spring’s creek, so people dug wells.

Then, the wells got infested with grasshoppers.

And the town grew, and grew, and grew again.

“Very soon you had to bring water from further away, and ultimately to the
Western Slope which is a couple hours drive of here.”

Today, Colorado Springs pipes water through the Rocky Mountain range.

Doing the extraordinary for water is kinda ordinary for Colorado Springs.

Its latest pipeline project is called the Southern Delivery System, and it’ll pump nearly
80 million gallons into town each year – and it’ll pump that water forty five miles –
completely uphill.

Impressive, but some people are asking tough questions about it.

“Our concern with this project is the greenhouse gas emissions that it would
contribute to.”

Stacy Tellinghuisen is with Western Resource Advocates, a Colorado environmental
group.

She says there’s a connection between pumping water uphill and a large carbon
footprint.

“Water is heavy. Pumping it over a great distance takes a lot of energy, and
in the process it would require something along the lines of 60 MW of power,
which is about a tenth of a power plant.”

And, for the most part, the utility burns natural gas and coal to generate power. Both
emit carbon dioxide, a greenhouse gas.

Tellinghuisen says Western cities are considering at least five other water pipeline
projects, some with even larger carbon footprints.

She wants Colorado Springs to set an example by using dedicated low-carbon sources
like wind power for its water pumps.

I ask the Colorado Springs Utilities about that.

Keith Riley helped plan the Southern Delivery System.

“We think there are some ways we can minimize the carbon footprint by
looking at some new technologies.”

Riley says there were lots of environmental regulations to wade through before the
Southern Delivery System got approved.

But a large carbon footprint doesn’t disqualify utility projects.

Riley says, even if carbon were considered, the project might have gone forward
anyway because the city’s expected to grow over the next few decades.

“Water is the essential element for all of us, so when it comes to that level of
sustaining our own lives, then you get to some trade-offs on what we’re
willing to do to keep ourselves alive where we we live, where our cities are.
No matter what happens, we’ve got to move water to Colorado Springs, and
we’re uphill from the river, so we’ve got to get the water uphill one way or
another.”

Riley says Colorado Springs Utilities is considering low-carbon renewable power for its
new pipeline.

But it’ll be expensive, and no one’s stepped forward with all the money.

Other Western cities are engineering clever ways of moving loads of water around,
too. And it’ll be a political and financial challenge for them to pay for the carbon
footprint.

Today begins “Fix a Leak Week.” It’s probably not in your calendar. It’s a new effort from the US EPA to encourage people to take a closer look at their plumbing. Tamara Keith reports:

(sound of dripping)

It turns out that drip drip drip of a leaky faucet can really add up.

(sound of toilet running)

A running toilet can waste up to 200 gallons a day.

Michael Shapiro heads the water division at the EPA.

“A typical home will leak up to 11,000 gallons a year. About the amount of water that will fit into a home swimming pool, for example.”

Most people can handle doing the repairs themselves. Jim Loviss is the plumbing manager at Strosneiders Hardware in Bethesda, Maryland.

“Sometimes it’s a washer, sometimes it’s a hose or a supply tube. Most times it’s simple. It’s being able to shut the water off and find out where the problem is and solve it.”

But, he’s not expecting a rush on washers and toilet flappers just because the EPA has declared it “Fix A Leak Week.”

One group wants part of the economic stimulus package to plug up some leaks. It says old toilets and leaky water pipes below city streets are wasting water. Chuck Quirmbach reports:

The group is called the Alliance for Water Efficiency. It’s made up of plumbing manufacturers, contractors, city water systems, and enviromental groups.

They want about ten billion dollars of the economic stimulus package to go to shovel-ready projects that conserve water.

Alliance board member Susan Stratton says the work could include everything from century-old city water pipes to replacing many older, water-wasting toilets in private homes.

“This requires the skills of a plumber and it requires retailers and wholesalers to deliver products. These are things we know how to do. There are people in the work environment who have these skills and can ramp up pretty quickly.”

Stratton says cutting water use would also save energy by reducing power use at water utilities.

Straining Water Supplies in the Southwest

  • Nancy and Dave Tom bought this home near Apache Junction, Arizona. They have to haul all the water they use with their pickup truck, so they quickly learned how to conserve. (Photo by Mark Brush)

Many areas in the Southwest are booming. With all this new
development, pressures on water supplies are growing. Mark Brush takes
a look at the lengths people go to, to get water in the desert:

Transcript

Many areas in the Southwest are booming. With all this new
development, pressures on water supplies are growing. Mark Brush takes
a look at the lengths people go to, to get water in the desert:


Nancy and Dave Tom used to get their water from a city water supply.
That was back when they owned a home in Tempe, Arizona. Like a lot of
people in the area, they had a pool, plants that needed water year
round, and a green lawn out back. Not exactly a desert scene. It took
a lot of water to support their lifestyle.


But life in Tempe was getting crowded. And when somebody rang their
doorbell and offered to buy their house for almost twice what they paid for
it, they jumped at the chance to move to a smaller town.


(Sound of birds)


They found a house for sale just outside of Apache Junction. It’s a
small city in the desert about an hour’s drive from Phoenix. The house
is at the foot of a dry mountain range and has spectacular views. But
the house didn’t have city water service:


“When we saw this piece of property we pretty much fell in love with it
immediately. And it was stated in the multiple listings that you did
have to haul water. And that the water trailer conveyed with the
property (laughs).”


(Sound of hooking up the truck)


To get their water, Dave Tom hooks up a trailer with a big plastic
water tank. He tows the trailer about 4 miles into Apache Junction.
There’s a water filling station here. He gets about 90 gallons of
water for each quarter dropped into the machine:


(Sound of truck parking)


“I’ve got my four quarters here – we’re going to put it in the vending
machine and have at it.”


(Sound of quarter and water rushing)


He makes about two trips a week, so he figures they’re using about 600
gallons of water a week. That’s quite a bit less than the 6000 gallons
they were using in Tempe.


Some of the things they did to cut back were obvious. Since they no
longer had a pool – and they didn’t water a green lawn – that helped.
But in their new place, they also bought a high efficiency washer and
dishwasher. And, when they don’t have guests around, they cut down on
the number of times they flush the toilet.


And they’re not alone in trying to cut back on water use. Even their
neighbors who have a well are really careful with their water. Phil
Reinhart lives just up the road. He’s rigged up a system of gutters
and pipes to catch rain water:


“You see it drains the front of my house and it comes down these
gutters into these storage barrels. And then I have a little pump that
I use and a little twelve volt battery that I use to pump my washing
machine full and then my washing machine then discharges into my citrus
trees – this is a lemon – here, take a lemon back with you.”


Reinhart is careful with his water. And he’s worried that the
population boom will put a strain on his well.


(Sound of water)


The tank on David Tom’s trailer is full. He tries to shut the water
off:


“Alright we’ll push the shutoff button – and watch out, you’re going to
get wet… no the shutoff isn’t working. We’re going to dump 25 to 30, maybe 40,
gallons of water, which to me it’s a shame they need to come down and
fix this.”


(Sound of water flowing)


A lot of this water spilling onto the ground has traveled a long way to
get here. The Central Arizona Project pumps water from the Colorado
River 230 miles away.


“Rather than a river than runs downhill by gravity, we’re a river that
runs uphill by pumps. We’re the largest electric consumer in the state
of Arizona.”


Sid Wilson is the general manager of the Central Arizona Project. He
says most of the water pumped into this region is used for farming.
But with rapid development, that’s expected to change. More water will
be used to service the new homes sprawling out into the desert.


“The CAP right now provides 40% of the water to this area, 40%, and that will increase
some over time.”


Wilson says people are going to continue to move to the Southwest. So,
future water supplies will have to be developed.


Back at their home near Apache Junction, Dave Tom has finished filling
up their underground storage tank. It’s taken him two trips with the
trailer.


(Sound of gurgling)


His wife Nancy says their new home has changed the way they think:


“Life out here in the desert has given me a greater appreciation for
water. There’s a part of me that says this is how everybody should
live in the desert. That they should have that awareness of their
water usage and embrace the fact that you live in the desert rather
than trying to change it into a lush tropical paradise.”

Ten Threats: Hidden Costs of Invasives

  • Foreign ships like this one from Cypress are known as "Salties" around the Great Lakes. These ships are responsible for bringing aquatic invasive species into the Lakes, and we're all paying a price. (Photo by Mark Brush)

In looking at these threats to the Great Lakes, almost everyone we surveyed agreed the worst threat was alien invasive species. Shipping goods in and out of the Great Lakes has helped build the major cities on the Lakes. But shipping from foreign ports has brought in unwanted pests. Zebra mussels are probably the most infamous, but there are more than 160 aquatic species that have invaded the Lakes and changed them, almost always for the worse. So why can’t we keep them out?

Transcript

Today we begin an extensive series called “Ten Threats to the Great Lakes.” The Great Lakes Radio Consortium’s Lester Graham is our guide through this series:


In looking at these threats to the Great Lakes, almost everyone we surveyed agreed the worst threat was alien invasive species. Shipping goods in and out of the Great Lakes has helped build the major cities on the Lakes. But shipping from foreign ports has brought in unwanted pests. Zebra mussels are probably the most infamous, but there are more than 160 aquatic species that have invaded the Lakes and changed them, almost always for the worse. So why can’t we keep them out?


Well, let’s say I import widgets.


(Sound of widgets dropping into a cup)


I’ve been getting widgets from somewhere in Asia, but I found out I could get widgets from an eastern European company for a dollar-a-widget cheaper. The factory there can ship them directly to my warehouse in Great Lakes City, USA by ship across the Atlantic and into the Great Lakes.


Pretty good deal. I get good widgets, the shipping costs are cheaper, my profits go up, and it means cheaper widgets at the retail level. Everybody wins, right?


Well, the ship that brought the widgets also brought an alien invasive species that stowed away in the ship’s ballast. A critter that’s native to eastern European waters is now wreaking havoc on the Great Lakes ecosystem.


Aquatic alien invasive species that have invaded the Great Lakes now cost the economy an estimated five billion dollars a year. Five billion dollars of what’s considered biological pollution.


So, who’s paying the price?


Cameron Davis is with the environmental group Alliance for the Great Lakes.


“Unfortunately, in most instances, who pays for those hiddens costs are you and me. We pay for our water agencies to have to clean zebra mussels out of their pipes, we pay our agencies through taxes to have to keep Asian Carp out of the Chicago River, we pay through our taxes in any number of ways to try to fight these invaders.”


So right now, taxpayers and utility ratepayers – even those who never bought a widget and never will – are paying the price. Davis says that’s just not right.


“One of the things we need to do is make sure that those ships are paying full cost for everything that they bring, not just the widgets, but the stowaways like the zebra mussels, things like that that they have on board.”


So, why target the ships?


Dennis Schornack chairs the U.S. Sector of the International Joint Commission. The IJC is a bi-national agency that monitors a water quality agreement between the U.S. and Canada. Schornack says that’s the way it usually works: the polluters pay.


“The cost of the impact of these unwanted creatures is something that’s not baked into the price charged for the widgets. So, somewhere that external cost needs to be captured back into the price. The ship owners themselves are the likely target to pay for this through a permitting fee which, of course, they will pass on to their customers, the people who made the widgets.”


So all of us who buy widgets end up paying a little more, but paying permits and fees could cost shippers more than they can afford. George Kuper is with the Council of Great Lakes Industries. Kuper says he understands the first impulse is to make the shippers pay.


“The problem with that, of course, is the shippers were already close to non-economic as a method of transportation, which puts us right up against an environmental challenge because shipping is by far the most environmentally un-intrusive method of moving large amounts of materials.”


Kuper says using other methods of transportation such as trains or trucks to move that cargo from East Coast ports might burn more fuel and cause more pollution.


But of all the shipping on the Great Lakes, only six percent of the tonnage is carried on ocean-going vessels. The rest is transported on Great Lakes carriers that never leave the lakes and don’t bring in new invasives. So, the question is this: is that six percent of cargo worth the damage that aquatic invasive species cost each year.


Many experts say there is a fairly simple answer to all of this. Technology is available for cargo ships to eliminate invasives from their ballast tanks. Requiring those ships to use that technology would likely add some to the cost of every widget, but supporters of the idea say it would greatly reduce the environmental cost to the Lakes.

New Drinking Water Rules Proposed

Federal plans to reduce exposure to lead and copper in drinking water could mean more monitoring of public water supplies. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

Transcript

Federal plans to reduce exposure to lead and copper in drinking water could mean more
monitoring of water from public water supplies. The Great Lakes Radio Consortium’s Chuck
Quirmbach reports:


The U.S. EPA says a lead contamination problem in the District of Columbia will prompt several
changes to federal rules on lead and copper in the nation’s drinking water supply. David Denig-
Chakroff is on a committee of the American Water Works Association that looks at lead
contamination. He says one of the biggest changes might be more monitoring of water when
local suppliers change water sources or the treatment process.


“They really need to go back and make sure that’s not changing the corrosivity of the water and
potentially increasing lead or copper corrosion.”


More corrosion from the pipes can lead to more lead and copper coming out of the tap. Lead can
build up in the brain, kidneys and red blood cells. The greatest risk is to young children and
pregnant women. The EPA says its formal proposals for updating the lead and copper rule will
be ready next year.

Outdoor Lab Forecasts Global Warming Effects

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now. They’re doing that by pumping higher levels of CO2 and ozone into stands of trees. The Great Lakes Radio Consortium’s Mike Simonson visited the experimental forests and has this story:


(sound of “quiet area”)


The north woods of the Great Lakes states are stands of millions of acres of pine, maple, birch, and aspen forests. It’s a perfect place to try to figure out how trees will react to the higher levels of ozone and carbon dioxide scientists expect in the future.


(sound of beeping fence gate)


The first thing you notice at Aspen Free Air Carbon Dioxide Enrichment Project – Aspen FACE for short – is two huge tanks inside the fenced in enclosure. Each one is bigger than an 18-wheel tanker truck. They’re full of carbon dioxide… CO2. So much CO2 is used in this experiment, the tanks are filled twice a day.


(sound of filling tanks)


If you looked at the site from an airplane, you’d see 12 circular tree stands surrounded by 30 foot high pipes. Those pipes pour CO2 or ozone gases or both into the air surrounding birch, sugar maple, and aspen trees. The scientists know that greenhouse gases in the earth’s atmosphere have been increasing. They believe two centuries of industrial pollution has contributed to the problem. And they expect the CO2 and ozone levels to double by the end of this century. They’re raising the level of greenhouse gasses in different mixes to see what the predicted levels will do to forests.


This open air project is different than previous experiments. David Karnosky is with Michigan Tech. He’s the Project Manager for Aspen FACE. He says before these kinds of projects, they just tested trees inside places like greenhouses.


“We needed to get out of those chambers. We needed to have a more realistic, real world sort of situation where we had multiple trees. We wanted real intact forest communities. We didn’t want to have just a small number of trees inside of a chamber.”


The United States Department of Energy launched this experiment in Wisconsin’s northwoods seven years ago. Karnosky says they’re learning how the trees react to the higher CO2 levels, and that could shape the future of the world’s timber industry.


“Who will be the winners? Who will be the losers? Will aspen or birch or sugar maple? In northern Wisconsin here we’ve got probably 40 million acres of those species mixes. What’s going to happen under elevated CO2 in the next 100 years? Will these forests remain as they are?”


(sound of driving on gravel)


Driving to one of the experimental circles, we pull up to a ring of trees. Mark Kubiske is one of the two full-time on-site researchers.


“Now this particular ring is an elevated CO2 plot. CO2 is delivered through this copper pipe. It runs to that fan, there’s a large fan right on the end of that gray building.”


The scientists have found that trees in the CO2 circles grow 30 percent faster than trees without the gas.


“The trees are larger in diameter, they’re straight, they have lots of leaf area, they just look very healthy. That is just in tremendous contrast to the ozone ring. We’ll go up around the corner and look at one.”


Nearby another circle of trees is not doing nearly as well. The trees are skinny, twisted not as tall as the other sites. Higher ozone levels are hurting the trees.


At the sites where pipes emit both ozone and CO2, the tree growth seems normal – except for some stunted maple trees. The leaves of the aspen and birch take in much of the CO2, convert it to sugar which goes to its roots, eventually becoming a natural part of the soil. That suggests forests may help alleviate gases that cause global warming. The Project Director, David Karnosky says CO2 and ozone appear to cancel each other out. But he says it’s too early to draw any firm conclusions. Ultimately, he says governments will be able to look at this glimpse into the future and try to come up with emissions policies that help.


“The whole issue of the Kyoto protocol, our government not signing off on that. There’s been some relaxing of the feelings from what I’ve seen from the President’s report now that they’re beginning to realize that elevated CO2 is having an impact on global warming and could be impacting our plant communities.”


Karnosky says it’s possible that besides reducing emissions, governments might determine that planting more trees might be very helpful in reducing greenhouse gasses worldwide.

Seeking Answers to Spring Sewage Dumpings

  • Sewers like these were leaking this spring in Milwaukee according to a task force employed by the mayor. He says fixing the problem may be expensive. (Photo by Bob Smith)

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the cleanup burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach explains:

Transcript

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the clean-up burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Several cities dumped sewage into the Great Lakes during heavy rains this spring and summer. Milwaukee’s overflow total was about five billion gallons. A task force set up by Milwaukee’s mayor concludes much of the problem came from rainwater leaking into the sewer system through illegal hookups and cracked pipes between homes and sewer mains. Mayor Tom Barrett says reducing the so-called infiltration and inflow, or, I and I, will be expensive.


“Well, we’re obviously going to have to put more dollars into I and I in Milwaukee. The city has done that, we’re doing more in this budget, we’re going to continue to do more… I think each of the communities is going to have to face that issue.”


The “communities” are the roughly 30 smaller cities that use the Milwaukee sewer system. Wisconsin’s attorney general is trying to ge the city and suburbs to work together. Milwaukee and many other Great Lakes cities are also asking the U.S. government to spend more money on reducing sewer overflows.

Epa Calculates Illnesses Caused by Sewage Overflows

Sewage overflows during heavy rains have long been implicated in
illnesses in people. For the first time, the Environmental Protection
Agency has come up with an estimate of just how many people are getting
sick from swimming at contaminated beaches. The Great Lakes Radio
Consortium’s Tracy Samilton reports:


The EPA estimates that somewhere between 3,500 and 5,500 beachgoers get sick
every year when untreated sewage is flushed into rivers, streams and lakes
by heavy rains. The EPA’s Ben Grumbles says the report is another reason
for cities to fix their aging sewage systems – despite the high cost.


“And it can literally add up to hundreds of millions, a couple of billion dollars, for
very large cities, to fix the problem for the long-term.”


Grumbles says many communities can avoid that bigger expense by investing
in new technologies to better manage existing systems – and keeping pipes
well-maintained and free of debris.


Environmental groups say they hope legislators are listening. Congress just reduced
the fund from which communities can get loans for sewer projects by 500 million dollars.
